STEM WINDING AND SETTING WATCH.

Specification of Letters Patent.

Patented Dec. 4, 1906.

Application filed April 3, 1906. Serial No. 309,670.

To all whom it may concern.-

Be it known that I, LARs HAUBROE, a citizen of the United States, and aresident of New Haven, in the county of New Haven and State ofConnecticut, have made and invented certain new and useful Improvementsin Stem Winding and Setting Watches, of which the following is aspecification.

My invention relates to an improvement in stem winding and settingwatches, and more particularly to the mechanism employed for shippingthe clutch to engage with the winding or setting trains, the objectbeing to simplify and cheapen the cost of this mechanism, to therebyrender it more effective and less liable to get out of order. Heretoforein mechanism devised for this purpose it has been usual to employ twosprings, one having a greater tension than the other, so that when thewinding stem or arbor is adjusted lengthwise the spring having thegreater tension will overcome that of the other. In other instances asingle or differential spring has been employed; but in all thoseinstances of which I am aware one portion of the spring is employed toovercome the tension of the other, usually by operating upon levershaving arms differing in length.

One object of my present invention is to avoid the action of one springagainst the otherthat is, when it is desired that the shipping-levershall lower the clutch to engage with the setting-train the tension ofthe s rin on said shipping-lever, which normally holds the clutch inengagement with the winding mechanism, will be entirely removed, therebyimposing no work on the second spring other than to exert such tensionon the shipping-lever as will cause the latter to lower the clutch,which freely slides on the winding-stem; further, to so constructandarrange the parts that when it is desired to raise the clutch on thewinding stem to engage with the winding mechanism the spring whichindirectly retains the clutch in its raised position will not exert itstension on the shipping-lever until such clutch has been raised intoengagement with said winding mechanism. By thus avoiding the necessityof one spring overcoming the tension of the other in order to performits functions it is possible to use a much lighter spring for raisingand lowering the clutch than has heretofore been possible. I

{ With these and other ends in view the invention consists in certainnovel features of construction and combinations of parts, as will behereinafter fully described, and specifically pointed out in the claims.

In the accompanying drawings, Figure 1 is a view of a part of awatch-movement, showing the improved mechanism in its windingadjustment. Fig. 2 is a similar view showing the mechanism in itssetting adjustment. Fig. 3 is a sectional view taken on the line 3 3 ofFig. 2, and Fig. 4 is a modified form of the locking-lever andclick-spring.

Referring to the drawings, A represents a watch-case center of ordinaryconstruction, in which is mounted the front plate B of thewatch-movement, said plate being provided with the opening C toaccommodate a portion of the winding and setting mechanism. The movementis provided with the usual winding stem or arbor D, adapted to rotate towind and set the movement and also adapted to be vertically adjusted bya push or pull upon the crown, (not shown,) usually secured to the outerend thereof, the stem being held in its different adjustments by amechanism contained within the pendant. As such parts are of the usualconstruction and well known to those skilled in the art and form no partof the present invention, no illustration or further description thereofis necessary.

On the winding stem or arbor is mounted the clutch E, adapted to movevertically on the winding-stem D and rotate therewith, said sleeve beingprovided with the groove e to accommodate one end of the shippinglever,at its upper end with the ratchet-teeth e to engage with similarratchet-teeth on the winding-pinion F, and at its lower end with theteeth-e on its lower end to engage with the teeth of the setting-pinion(not shown) when said clutch is lowered into its setting adjustment. Asis usual with mechanism of this character, it is necessary to raise andlower the clutch E to engage with the winding and setting trains,respectively, and in order to effect this movement of the clutch on thewinding-stem D, I secure to the plate B the shippingdever G, pivoted atg and comprising an arm H, the extreme end of which fits in thecircumferential groove e on the clutch, and an arm J, the inner edge 1'of which is recessed or curved for the purpose 1 hereinafter described.When the arm J of and in which osition the end 0 of the shipping-leveris moved outwardly, the arm H will be lowered, thereby lowering theclutch E into its setting position, as illustrated in Fig. 2, and whensaid armJ is moved inwardly the arm H will be raised, thereby raisingthe clutch E into engagement with the winding-pinion F, as illustratedin Fig. 1.

To operate the shipping-lever G, I pivot to the plate B at 7c thelocking-lever K, one end or arm L of which projects below and engageswith the lower end of the winding stem or arbor D, the other arm Mwithin the curve or recess of the lever J when the parts are in thewinding adjustment, as illustrated in Fig. 1. en, however, the Windingstem or arbor D is pulled outwardly, as illustrated in Fig. 2, and thearm M of the lever lowered, the extreme end of the latter will engagewith the lower end of the arm J, thereby forcing the same outwardly andthe arm H and clutch E downwardly, thereby locking the lever G andclutch E against movement while the parts are in the setting adjustment.In order to effect this downward movement of the arm M, outward movementof the arm J, and downward movement of the arm H and clutch E, I employa spring N, resting in the recess n in the plate B, one end of saidspring being secured under the screw n and t e opposite end bearingagainst the pin or projection n formed on or secured to the outer end ofthe arm M, the tendency of said spring being to lower the latter so thatwhen said winding-stem D is pulled upwardly, as illustrated in Fig. 2,the tension of said spring N will lower the clutch E into its set tingposition. By reason of this construction and arrangement of parts thespring N may be a comparatively light one, as it is in no way operatingagainst the tension of any other spring, the work to be performedthereby being simply to lower the arm M, the arm H, and, in turn, theclutch E, and as these parts move or slide freely on their bearings thetension of the spring may be a very slight one. When now the windingstem or arbor D is forced downwardly, as illustrated in Fig. 1, itcarries downwardly with it the arm L, thereby raising the arm M into thehollow or recess of the arm J, and at the time that the winding-stem Dhas almost reached its lowest adjustment the end 0 of the spring 0strikes the outer side of the arm J and forces the latter inwardly, thismovement effecting an upward movement of the arm H, carrying with it theclutch E. This spring 0, usually termed the click-spring, is preferablymade in one piece with the lever K, a space being left between theextreme ends of the arm M and spring 0 for the entrance of the curvedarm J when the parts are in their winding adjustment, as illustrated inFig. 1, said spring bears very lig J, thereby tly upon said arm thelower end of said 1 to engage with the other arm of said lockingi leverto lower the same, a shipping-lever, one

holding the clutch E in yielding engagement with the pinion F. When thestem D, how ever, is pulled upwardly or outwardly and the arm M loweredby the spring N, the end 0 of the spring 0 is immediately lowered withsaid arm M and withdrawn from contact with the arm J, whereby to allowthe spring N to perform its functions without the necessity of workingagainst the tension of said spring 0, the latter coming into play atsuch time only as when necessary to raise the clutch into its windingposition. During such movement of the parts it will be understood, ofcourse, that the tension of the spring N on the arm M is overcome by thedownward movement of the stem D on the arm L, so that at no time iseither spring called upon to work against the tension of the other.

Instead of forming the cliclespring O in one piece with thelocking-lever K it will be understood that it may consist of a separatepiece, as illustrated in Fig. 3 of the drawings, K representing thelocking-lever and O the click-spring secured thereto.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is

l. The combination with a winding stem or arbor, of a clutch slidingthereon and retating therewith, a locking-lever, one arm of whichengages the lower end of said stem, a spring engaging with the oppositeend of said locking-lever and adapted to lower the same, ashipping-lever, one arm of which engages with said clutch, and aclick-spring connected with said locking-lever and adapted to alternatewith said lockinglever to engage with the other end of saidshippinglever when said clutch is raised and lowered, substantially asdescribed.
